To go along with the Flitetest forum's challenge Getting stupid with the Tiny Trainer, here's a video of my first flight and crash of the FT Tiny Trainer. I thought for this flight I'd be trying to get it trimmed out, but I spent more time going all over the place with it. Damage was pretty minor on the crash. I originally imagined this plane as kinda floaty but really on 3 cell power it's kind of a handful. Enjoy!

Building the P-51B takes two wheels .75 in. thick and 3” in diameter. The tail wheel is 1” in diameter and about a half-inch thick.

Yes I could have spent $12 to buy Williams Brothers excellent balloon tires. However, I could get some balsa stock for $4.

After research I built the wheels in layers. The hubcaps came from a thin sheet of modelers plastic—1/32” maybe. I used a 1/4” in. paper hole punch to make the revolver-patterned holes. They usually take 8 triangles, but I never was satisfied with test hubcaps. The plastic is crisp.

I don’t have a lathe or a way to screw these onto my drill. I cut the ply and balsa circles out using a micro-blade saw. I got close to the line. The 1/8” ply wanted to splinter. The 1/16” ply sheets were really solid.

The layers alternated left to right: 1/8” balsa, 1/16” ply, 3/32” balsa, 1/8” ply, 3/32” balsa, 1/16” ply, and 1/8” balsa. I carefully marked a center point on each circle poking they the template cut from the plans. On the outside balsa disks, I cut out holes for the hubcaps using the template from the plans. They were difficult to get truly circular.

The tailwheel was only one 1/8” ply middle and 1/8” balsa with the circles cut out. I did not add a hubcap to the tailwheel...yet.

After gluing, I stuck a T-pin thru the pre-drilled center holes and sanded the perimeter of the wheels. I taped a sheet of 100 grit sandpaper on my sork bench. I rocked the wheels while sanding. It was hard to sand the ply disks....Continue Reading

After several conversations on how to set up the throttle for F5J I quickly found that there is no one stop set of instructions to do this. ALES and F5J are the electric sailplane events where having an arming switch tied to throttle is very beneficial. ALES (altitude limiting electric sailplane) can use the standard motor setup in the DX9 / DX18 using the bind button or switch designated to power on the motor to 100%. That is pretty standard. What happens when you need to launch with a low power setting? Throwing the sailplane and going to the slider on the right or left is cumbersome at best. Another solution is to set a motor curve with a value on the low throttle setting. When you enable the arming switch it turns the motor on and you can then fly away with ease by not fumbling for the slider switch. Using a 3 position switch to select one of 3 motor speeds: loiter, cruise and climb (low medium and high) will make it easier to fly these events.

I have attached a series of instructions that will give you the basic idea behind what to do for this programming. With so many ways to do things this is just an example. You can use this to tailor toward your needs using various other switches.

Same settings as for the Turtle as before but I had to do some color grading, maybe because it was a bit cloudy.

The Hobbymate Asteroid is a new 3 inch quadcopter that is available in kit, BNF or PNF formats that is available with motors and electronics suitable for 4s or 6s (!) operation. The purpose of the blog linked is to show how I have built in close detail and how I have set up betaflight software for optimal performance. Note you can spend an extra $30 to have this build with a FRSKY receiver but I always like to tinker and optimise my build which is why I have chosen this path.

Personally I prefer to build myself, part of the fun of the hobby. Documentation not so much but now it's done!

www.quadifyrc.com/reviews/hobbymate-asteroid-3-inch-quadcopter-build-tutorial-and-betaflight-pids-etc

I'll follow up with the review shortly but boy this is crazy quick in a straight line. With a CNHL 650mah 4s and a 80% throttle limit it's faster than anything I've flown. I plan to put a GPS on to verify.

Updated on May 8th, 2019: This is the latest 10th anniversary version of RMILEC NB20 20 Channel UHF LRS System. Comparing to previous versions, it is not only much easier to install, but the heat dissipation and positioning function also have been greatly improved.

Product link: https://fpvmodel.com/products/new-rm...m-complete-set

The NB20 system adopts the latest RF technology, providing very high adjacent channel rejection ratio and anti-blocking performance, which gives rise to the outstanding anti-jamming capability of the new system.

The NB20 receiver can detect the frequency and amplitude of EMI interference with unbeatable accuracy and precision based on the extremely low self-noise of -125dBm. The RF performance of NB20 system surpasses the older 4047 systems several orders of magnitude.

Furthermore, NB20 system takes high-speed processor for signal acquisition and output with very high precision. Its high efficiency transceiver can make full use of band width limitation and spend shorter time to work out data exchanging,and frequency calibration.

As for operation, The NB20 system is compatible with any receiver to construct a signal relay system. It is highly compatible with mature products on the present market, such as FUT, JR, HITEC, TDF, FS, XINYI etc. There is no need for consumers to change the old remote control system or any parameter settings to directly extend the remote control range. PWM output-and-input is one-to-one. It can relay...Continue Reading

I'm watching the news show Amanpour and Company on US public broadcasting and reading the E-Flite Valiant™ 1.3m BnF Basic thread. The subject on Amanpour is Chinese detention camps in West China for the local Uyghur (pronounced weeger) people. The Uyghur people are Muslim. Apparently they are being persecuted by the majority Han Chinese who have recently migrated in large numbers to the Uyghur home land in Western China. This made me realize how small my RC hobby is compared to how much time I put into it.

I was asked by several folks to see if I could bring back my profile Dyna-soar kit I used to do as a rocket glider, due to the loss of true depron 6mm, the depron aero wasn't stiff enough to continue the kit and MPF was not uniform or stiff enough either. I was able to buy a supply of 9mm depron when rcfoam went out of business, so for a limited time I'm redoing the kit, calling it the Lifting Body, even though this is more of a small winged boosted glider than a true lifting body, it still fits the definition. Profile gets you maximium wing area, the 9mm is heavier but is definitely robust. Available from dynasoarrocketry.com

Here's a pic and video, 21" wingspan, 31" length, 14 oz rtf using a 24mm E-6 rocket motor. This is the same size as on the cover photo on top of the Titan II stack, but without a full fuse to make kitting/construction and flight times better. It can also be had with two other fuse/wingtip profiles to simulate X-24 or HL-10 styles

This subject certainly is unique in NZ – it’s the Tumeke – the only pusher tug in the country. For a kick-off, it’s tiny, only 9m long (27ft). That’s smaller than a small truck. It could go on the New York ATB as deck cargo.

And it’s not pretty – some might even say ugly. It certainly is ‘challenged’ in the looks department.

It was built in 1995 by Northeastern for Benson Brothers (to a Chris Benson design) and is now based out of the major port of Tauranga. It spends most of its time pushing a harbour works barge and dredge around the small provincial ports on the Coromandel Peninsular, making and repairing marinas.

Tumeke means ‘startled’ and I’m sure you would be, in a high sea. It doesn’t look as if it would be very stable without a barge attached.

Construction was pretty straightforward, I started by drawing up some plans based on several photos I found online, and then the process followed my usual methods. As the model is so small the build didn't take too long or present many problems.

A complete build log is at: http://modeltugforum.com/index.php?topic=6435.0...Continue Reading
